NEW YORK (TheStreet) -- TerraForm Power(TERP) - Get Report stock is gaining 4.45% to $10.80 on heavy trading volume late Thursday afternoon after Brookfield Asset Management (BAM) revealed a 12.13% stake in the company yesterday.

Brookfield acquired more than 11 million of TerraForm's Class A shares for approximately $98.5 million, according to a regulatory filing cited by Bloomberg.

The Toronto-based alternative asset manager said it entered into swap agreements to possibly buy nearly 11.6 million extra shares. The firm also said it would be interested in buying SunEdison's Class B shares, which give control over TerraForm.

TerraForm is one of SunEdison's (SUNEQ) yieldcos.

"It seems like an inherent positive that a major and well respected asset manager, more so than, say, a hedge fund, is seeing value in TerraForm," Matt Tucker, an analyst at KeyCorp, told Bloomberg.

Brookfield's affiliates are also making efforts to acquire TerraForm shares, according to the filing.

Bethesda, MD-based TerraForm is an owner of power generation assets.

About 5.52 million of the company's shares changed hands by late this afternoon, above its average volume of 3.14 million shares per day.

Separately, TheStreet Ratings Team has a "Sell" rating with a score of D on TerraForm stock.

The company's weaknesses can be seen in multiple areas, such as its deteriorating net income and generally high debt management risk.
