Precise identification of rightly-priced stocks is the key to successful investing. However, in practice, overpriced toxic stocks and the correctly-priced stocks are intertwined in such a manner that it is difficult to distinguish between the two.
Generally, overhyped toxic stocks are susceptible to outside shocks. Moreover, these stocks are loaded with a high level of debt. The price of these stocks is artificially inflated. Nonetheless, the higher price of toxic stocks is only short-lived as it is higher than its true intrinsic value.
Investors are likely to benefit from precise identification of toxic stocks with the help of an investing strategy called short selling. This strategy allows investors to sell a stock first and then buy it when price falls.
While short selling excels in bear markets, it typically loses money in bull markets.
So accurately identifying toxic stocks and abandoning or short selling those at the right time is the key to safeguard your portfolio from big losses.
