Can These Megacap Stocks Double? Wall Street Thinks So

Of the nearly 120 companies with at least a $100 billion market cap, only three have a high-water Wall Street price target that implies a doubling in their respective share prices. Perhaps unsurprisingly, auto stock Tesla Motors (NASDAQ: TSLA) offers the highest implied upside, based on the beefiest Wall Street price target -- $1,471 a share -- as of this past weekend. If this price target came to fruition, we'd be talking about a 129% increase in Tesla's stock.
