Top 10 Stocks vs News Sentiment: Same 251% Return, Half the 2022 Loss
Holding the 10 largest US companies with a weekly equal-weight rebalance turned $100,000 into about $350,842 from January 2020 to October 20, 2026, against $260,067 for SPY with dividends. I then kept only the top 10 companies whose news over the previous 60 trading sessions was positive on average. The total return tied at about +251%, while the worst drop fell from 41.4% to 31.6% and the 2022 loss shrank from 37.9% to 18.9%.
Flipping the filter to negative news also cut the 2022 loss to 19.6%, and simply holding the top 20 with no news had the smallest worst drop of any version at 29.3%. Adding positive news to the top 20 lowered its return from +224% to +141% because it kept skipping Meta and Tesla while they rallied. News sentiment did not make the strategy better; the smoother ride came from owning more companies. Read the full results in the article.

0:00The simplest active trading strategy happens to beat the market.
0:03Instead of buying the S&P 500, which holds the top 500 US companies, I take only the top ten, and rebalance every week.
0:11Across almost seven years, that turned $100,000 into $351,000.
0:17The S&P 500, with dividends, got to $260,000.
0:22Last week I tested whether news sentiment predicts stock returns.
0:26A day out, a week, a month, a quarter, a year.
0:30I couldn't find a reliable edge.
0:32I didn't believe it.
0:33I wanted to see if news sentiment could make this strategy even better.
0:36So here's how I tested it.
0:37Same weekly rebalance.
0:40But instead of the ten biggest companies, I took the ten biggest whose news over the last 60 trading days was positive on average.
0:47Total return was a tie.
0:49251% with the filter.
0:51251% without.
0:53The difference was the ride.
0:55In 2022, the plain top ten lost 38%.
0:58The filtered version lost 19%.
1:00Its worst drop was 32%, not 41%.
1:04And it wasn't one lucky stretch.
1:06In every three-year window, the filtered version fell less.
1:10In 97% of them, it had the better risk-adjusted return.
1:14Then I flipped the filter and kept only companies with negative news.
1:18It cut 2022 almost exactly in half too.
1:21So I ran one more test.
1:23No news at all, just the 20 biggest companies.
1:26Its worst drop was 29%, the smallest of any version.
1:30Then I added positive news to those 20.
1:32The return fell from 224% to 141%.
1:37The filter kept skipping Meta and Tesla while they took off.
1:40So news sentiment didn't make this strategy better.
1:43The smoother ride came from owning more companies.
1:45The full results, and every company the filter skipped, are in the article.
