Apple is one of the biggest companies in the US, so it comprises a significant portion of large-cap index funds. If any of your 401K or other portfolio includes an ETF or other fund with large-cap US companies, you own Apple stock.
If you’re invested 100% in a simple S&P 500 index fund, your portfolio is over 6% AAPL.
If the judge is simply reporting that he held large-cap index funds during this time, I think this is a non-story. Even a 10% drop in a company that makes up 6% of your portfolio is going to be negligible in your overall finances.
On the other hand, if he had something strange like options on AAPL around the time of his verdict, that would be a huge concern. However, I think these stories would have led with those details if they existed.
This is probably nothing.
