Most investors want to put their money in equities but may not be able to afford large stakes in valuable companies with higher-priced stocks. For them, low-priced stocks could be attractive as these will enable them to buy more shares instead of just a handful of higher-priced shares for the same amount. For example, an investor willing to spend $10,000 can either purchase at least 500 shares of a stock trading under $20 or only 100 shares of a stock trading at $100.Additionally, stocks under $20 reap huge profits as an increase of as less as a dollar in share price adds 5% to the portfolio. This is in contrast to stocks priced at $100 or above, which see 1% or lower gains if shares move up by $1. Further, most of the low-priced stocks have high levels of liquidity, which give these stocks an added advantage. This means that cash can be converted quickly and investors could easily get their money out of the securities. In fact, trading in higher average daily volumes keeps the bid/ask spread tight and does not lead to extra cost for investors.And guess what, the recent market rout led by the tech selloff has provided investors a great opportunity to tap some of these stocks. The preference is not only limited to the stock world but can be felt in the ETF space as well. In fact, there are only a handful of ETFs that currently trade below $20 out of nearly 2,000 funds, suggesting that choices are limited for investors who like to get a decent number of shares from their investment (read: Beaten-Down ETFs to Buy After Market Rout). So, let us dig into some of the ETFs that are below $20 and are trading at a bargain price.
