BALTIMORE ( Stockpickr) -- M&A activity is back in the spotlight this week. Already in Monday's premarket, a handful of high-profile acquisition announcements are getting positive feedback from investors as they bid up shares of both the acquirers and buyout targets ahead of the market open at 9:30. That behavior is pretty telling about market sentiment right now: as investors feel increasingly positive about stocks, they're much more likely to bid up buying firms before they know the full implications of the deals.Instead, they're issuing a vote of confidence that management will do the right thing to increase shareholder value. As a result, we could see a surge in stock valuations this week as Wall Street gets its legs back. Last week provided us with a push above a significant market resistance level, with major bullish moves on Monday and Friday. This week, we'll attempt to capitalize on any upside action with a new set of Rocket Stocks plays. >>>5 Window-Dressing Stocks That Could Surge We're turning to stocks with rising analyst expectations to eke maximum sentiment out of the markets. I identify those stocks by running a quantitative screen that picks out companies with a recent series of analyst upgrades and a history of outperforming the Street's expectations. It's a methodology that's worked well for us in the past: Our list outperformed the S&P 500 by 83 basis points last week. That brings our total dominance over the market to 66.59% over the past 62 weeks that we've been keeping track of our Rocket Stocks' performance. This week, we'll attempt to continue our trend with 5 new stocks.
