ARK Innovation (NYSE:ARKK) — the top-performing ETF of 2021 — is down 21% this year, leaving those who bought at its peak feeling the pain. Catch up: What is an exchange-traded fund?

Despite underperforming in 2021 and seeing billions flow out of her ETFs, Cathie Wood continues buying dips on tech stocks, including Robinhood (NASDAQ:HOOD) and Twitter (NASDAQ:TWTR) — both falling over 40% in recent months.

In a post, Sachin Nagarajan — a data analyst at Morning Star — shared three reasons why ARK Invest isn’t for him:

• He’s already overweight growth stocks in other areas of his portfolio.
• He doesn’t have the stomach for volatility.
• He loves “forget-about-them” investments.

If you feel similarly, ARK might also not be for you. ARK’s ETFs focus on innovation and growth — a riskier area with frequent fluctuations.

• The past: Which is why ARK has fallen nearly 30% or more three separate times in the past seven years.
• The future: Interest rates are expected to rise in 2022 — which historically hurt growth stocks.

If you held ARK since its inception in 2014 — you would have achieved a 26% compounded annual return — double the ~13% annual return of the S&P 500 in the same time period. But volatility is the price to pay for higher returns.

The Joe’s Take: Eventually, growth stocks will fall hard enough where they start looking cheap again. These low points often present the best entry points for investors.
