NEW YORK (TheStreet) -- Shares of Twitter (TWTR) - Get Report were up in midday trading on Monday after Bloomberg reported that Disney (DIS) is considering a potential takeover bid. 

Twitter stock rallied 21% on Friday on speculation that Salesforce.com (CRM) or Alphabet's (GOOGL) Google unit might purchase the San Francisco-based social network. 

Earlier today, Oppenheimer downgraded Twitter shares, noting that a media company is the "most likely purchaser and would not pay meaningfully more than the valuation implied by our price target." The firm has a $17 price target on the stock.

Brian Sozzi of Real Money, TheStreet's subscription-based site for active traders, says would-be TWTR suitors should consider three key things before bidding for the social-media giant. Click here to see what they are.

Separately, TheStreet Ratings team rates the stock as a "sell" with a ratings score of D.

Twitter's weaknesses include a generally disappointing historical performance in the stock itself.
