What this transaction means for investors

Lantz Financial's doubling of its WINN position is certainly eye-catching. Not only did it push the ETF into the firm's 14th-largest position, but the purchases occurred while WINN traded near all-time highs. Since debuting on the public markets in 2022, WINN has delivered annualized total returns of 13.9%, compared with the S&P 500's 13.3%. However, before investors pile into the ETF thanks to its slight underperformance, there are a few things they might want to know first.

The main issue is that the Magnificent Seven equal 47% of WINN's portfolio, whereas this figure sits at 35% for the S&P 500. This isn't a dramatic difference, but it makes WINN a more concentrated bet on the tech-heavy holdings. Furthermore, WINN holds only 72 stocks, making it less diversified and more volatile than a vanilla S&P 500 ETF. On top of this issue, WINN charges a 0.57% expense ratio, which is multiples higher than most S&P 500 trackers. Lastly, WINN trades at 37 times earnings, due to its outsize exposure to the Magnificent Seven, while the S&P 500 as a whole trades at just 28 times earnings.

While I can understand Lantz's interest in WINN, I think individual investors would be better off picking their favorite stocks among the ETF's holdings rather than taking on extra risk to essentially match the S&P 500's returns.
