Big-Tech’s Key insights Apple for sure? Watch out "tax loss harvesting" This year, the seasonal trend in the US stock market is particularly strong. Although the Silicon Valley bank crisis at the beginning of the year brought some risks, the market found a new anchor - AI. In the second half of the year, the decline in inflation and the expectation of a "soft landing" led to the market's upward trend after a weak September. Big tech undoubtedly benefits the most. The combination of the seven giants accumulated more than 60% excess returns over the S&P 500 index in the middle of the year, and surprisingly maintained stability and even further growth during the volatility in the second half of the year, with current excess returns approaching 80%. Entering December, investors are particularly looking forward to the Christmas Rally, One important factor is that fund managers want to "boost performance" at the end of the year, maximize returns, and earn higher bonuses. And big tech stocks are still the undisputed top choice during this period of performance boosting. First, the "tax loss harvesting" effect. Fund managers avoid closing positions with high returns this year (because they have to pay taxes), but instead close positions with poor performance (because they can be used for tax deduction). This is a trading strategy (mainly in areas with capital gains tax such as the US and Canada) that intentionally generates "capital losses" to offset capital gains tax or personal income tax. Of course, this only delay the tax payment, not exemption. However, in the current high rate environment, reducing cash outflow as much as possible and reinvesting is one of the ways to achieve higher allocation efficiency and higher returns. It is worth noting that the "losses" that have already been closed this year cannot be offset against capital gains and can be deferred for future gains without expiration. All seven giants have had at least 50% or more returns this year, and even TSLA, which had a huge decline last year, has achieved returns of over 100% this year. It is obvious that closing positions at the end of the year may face higher taxes. Second, concentrated advantageous holdings for safety. Everyone now knows that inflation is falling and interest rates will definitely be lowered next year, so market expectations are very consistent and everyone wants to get ahead. However, there are still uncertainties about whether a "soft landing" can be achieved. Even if betting on interest rate cuts, it also depends on whether the economic environment "deviates." Therefore, investing in top tech companies carries lower risks to some extent while maintaining a certain proportion of holdings, thus "reducing risk." During the "Silicon Valley Bank" incident, companies like Apple and Microsoft received a lot of capital inflows, not because they were fundamentally more favorable but rather because they served as a "rest stop" during "market liquidity overflow." At the end of the year, when facing the same consistent expectations but also worrying about additional risks, choosing large tech companies offers a higher margin of error.
