Wondering why stocks rose the most in over three years in February? Bloomberg reports that $104 billion in repurchases were announced last monthโ€”the most since TrimTabs Investment Research began tracking the data in 1995. You can read the full story here. The highlights are below.

Even with 10-year Treasury yields holding below 2.1 percent, economic growth trailing forecasts and earnings estimates deteriorating, the stock market snapped back last month as companies announced an average of more than $5 billion in buybacks each day. Thatโ€™s enough to cover about 2 percent of the value of shares traded on U.S. exchanges, data compiled by Bloomberg show.

โ€œValuations are somewhat stretched right now, so itโ€™s puzzling a little bit to see this kind of activity,โ€ said Todd Lowenstein, who helps manage $16 billion at HighMark Capital Management Inc. in Los Angeles. โ€œIf youโ€™re a contrarian, this level of buyback activity spooks you a little bit because the track record is not impressive in terms of companiesโ€™ ability to buy stock at the right price at the right time.โ€
