It has been quite the volatile week for the markets. Investors saw the worst Christmas Eve in history in the markets, but that was followed by the single highest points gain in the Dow's history when it topped over 1,000 points in a single trading session. However, investors should keep in mind that percentage-wise, the Dow's swing doesn't even break into the top 20 highest percentage gains. TheStreet's Martin Baccardax and Katherine Ross discuss whether the algo's were to blame for the market rally and what caused the downturn on Christmas Eve.
