What is the difference between Momentum Trading and Value Investing?

Momentum Trading is a strategy in the investment world were traders will only concern themselves with the “hot picks” of the day, the high percentage and volume movers of that trading session. Traders in this methodology will look for assets that move a significant percentage on a given day, in high volume. This trading strategy is not a long-term or buy-hold type of strategy. Instead, traders will hold their long or short positions for only as long the stock is moving quickly.
Value Investing, on the other hand, is definitely more of a medium to long-term prospect. Value investors are specifically looking for undervalued stocks, those assets that traders believe are trading below their intrinsic values. Investors who employ this strategy believe strongly that the market overreacts to both good and bad news.
