$Western Digital(WDC)$ Sharing this order again. Was the sell call 0dte I mentioned earlier. Refer to previous post for the exact excution timing.
$WDC 20261002 407.5 CALL$ Sold 0dte at 407.5 for a tidy profit. Covered call within 4 hours earning 1.4k usd in total from stock gain and premium. Not bad for a fish bottom trade.  More like casino than trading. Haha

Cash-Secured Puts From Scratch — Including The 100 Contracts I'm Currently Getting Wrong

Mathematical Money | October 3, 2026 A few people have asked me to explain how I actually sell puts, so this is the whole thing from the beginning — what it is, how I choose strikes and dates, how to place the order without giving money away, and a live mistake of mine that illustrates the one rule everybody breaks. If you already sell premium regularly, the first section will be familiar. Skip to the ordering mechanics, because that's where most people quietly lose a chunk of their edge. What you're actually agreeing to Selling a cash-secured put means promising to buy 100 shares of something at a set price, by a set date, in exchange for cash today. You set aside the money to honour that promise — that's the "cash-secured" part — and the cash you receive is yours whatever happens. Two ou
Cash-Secured Puts From Scratch — Including The 100 Contracts I'm Currently Getting Wrong
$APP DIAGONAL 261023/261030 CALL 370.0/CALL 340.0$ Rolling down the short call position to squeeze more premium.
$SPCX DIAGONAL 261106/261030 PUT 148.0/PUT 145.0$ Rolling up and out to squeeze more premium
$IBIT 20261023 47.0 PUT$ Will explain in the next post for this position.
$ORCL 20261023 195.0 CALL$ Bought the leap a few weeks ago. Up and down and back to range. Now selling the short call leg to get back some coffee money. Same time can cover abit of the theta decay of the leap
$MARA 20261023 13.0 CALL$ Have approximately 50 contracts expiring above 14 today. Selling covered call in advance since it is not gonna be cross that strike today, not possible. 
$Western Digital(WDC)$ Bought the stock intra day trying to fish for bottom. News from Toshiba expanding may be overblown. Liquidation taking place throughout the day flushing all the leveraged holders.
$AVGO 20261023 400.0 CALL$ Opened the leaps a while ago. Left it hanging hoping to time it correctly. Who knows it keeps going back and forth in this range.  Decided to just open the short leg of the call option, hence forming a poor man covered call. The leap will act like the stock itself but now just gotta be careful that it doesnt get assigned if it crosses the strike of short call. 
$COIN DIAGONAL 261023/261009 CALL 180.0/CALL 175.0$ Covered call expiring in a week. Not much time value left. Rolling it up from strike 175 to 180 so that I gain the potential of $5 gain in stock price. The premium isnt a lot but at least its positive at $0.20. Coinbase price is still stuck in the upper boring zone of $180-$200. Can go to one of my posts regarding the levels im watching. Nothing much to do now, just extracting as much premium as I can from this counter while waiting for it to break 200. Cant really time it as the CEO himself also couldn't time it. But the best guess is the next earnings or regulatory approval or even next owning product that will increase its econ
$iShares Bitcoin Trust(IBIT)$ Shorting ibit at spot. Hedging the rest of my crypto positions for a bit. Same time also a sell put at a lower price.  Protecting profits and if btc goes up, the rest of my positions should cover the losses that this covered put will make.  Basically sell puts at 47 to get premium. Shorting the stock at 48.60. If it goes down and I get assigned at 47, I keep premium and the same time gain $1.60 on the short position.
$WDC 20261023 500.0 CALL$ Closing short call for a tidy profit. The toshiba news could be an over reaction. Closing this side of the pmcc. Looking at opening the short call again once the price recovers. Target is still approximately 500.

Would You Rather Fall 38% Collecting 5%, Or Fall 35% Compounding 15%?

Mathematical Money | October 2, 2026 The question people love to pose is a choice between two lives. Option one is around 5% a year, safe, limited drawdowns, sleep at night. Option two is 20%-plus a year, but you have to survive drawdowns of 50%. It's a good question and I was going to write it up as a straight either-or, until I went to check whether the first option actually exists. I don't think it does. What I measured I pulled daily closes for the usual "safe income" names and the usual "risky" ones over the same window — 20 December 2021 to 1 October 2026, which is 4.78 years and takes in a rate shock, a bear market and a full recovery. These are price returns and price drawdowns, so they exclude dividends, and I'll deal with that properly in a moment because it genuinely matters. St
Would You Rather Fall 38% Collecting 5%, Or Fall 35% Compounding 15%?
The question going round is what to watch in October — Fed policy, earnings, Treasury yields, or AI. My answer is none of those four, and I'll make the case with one number. September, measured two ways Take the S&P 500 as it's normally quoted, weighted by market capitalisation. It fell 0.58% last month. A nothing month, the sort you'd forget about. Now take the exact same five hundred companies and weight them equally, so Apple counts the same as the four hundredth name on the list. That version fell 5.18%. Same businesses. Same month. A gap of more than four and a half percentage points. The rest of the board agrees with the second number rather than the first — the Dow fell 4.33%, and the Russell 2000 fell 5.46%. The only thing that went up was the Nasdaq 100, at +3.21%, and that i

McDonald's Will Pay You 3.2% To Wait Five Years. The Ten-Year Pays 5.24%.

Mathematical Money | October 1, 2026 $MCD McDonald's is 32% below its February high and made a new low every single session last week. Plenty of people are asking whether this is the moment to step in. I don't own it, I've been watching it, and my answer is not yet. Here's the reasoning, fundamental and technical, including the part where my own framework got caught out. What actually happened on the 23rd This wasn't a market selloff dragging a good company down. McDonald's fell 4.8% on the day of its own investor day, which is a fairly unusual way to lose money. Management laid out a strategy called NEXT — roughly $8.5 billion of franchisee support through 2036, going into restaurant remodels, technology and operations, with targets for share gains in chicken and beverages and an operatin

$MARA DIAGONAL 261016/261030 CALL 14.0/CALL 13.0$ Rolling down and out. Getting $0.33 per contract. Taking the risk that it will be exercised.  Short term bearish on this counter. But long term I dont see any issues. Alot depend on btc now to drive the price but I do see some possibilities of AI driven news.
$MARA DIAGONAL 261009/261023 CALL 14.0/CALL 13.0$ Rolling down from strike 14 to 13. Getting $0.26 per contract for the extra time decay of 2 weeks more and closer strike price.

Coinbase: The levels I'm watching

$COIN Coinbase has always been one of my favourite stocks to do the wheel strategy because of the high IV and juicy premium. Was heavy in this counter (doing wheel only) in 2022-2024 and had a good run back then. Now I'm seeing good value in this again so just sharing the levels I'm watching and stratgey I'm implementing, not financial advice. $160-$180: Support zone. Most transactions happened in this band over the last 9 months. Weak hands exit, whales come in to grab. Boring Zone because not much movement and excitement. Best for the "wheelers". $145-$160: Liquidity grab zone. Volatile movements whenever it drops below this. Matches the 2025 April low and 2024 September low. Bounced off 4 times in total over the last 3 years. Reverts to above support zone quickly and looks like "planned
