Twitter Seen Below $28 by Bearish Structured Note Investors

Twitter Inc. will fall below $28 by June after surging as high as $50 in the company’s first five days of trading, according to structured product investors.

Nine of the ten most-traded securities listed on European exchanges and tied to the shares of the short-message Internet service are put warrants, whose buyers profit if the shares drop below a pre-defined level, according to data compiled by Bloomberg. Twitter raised more than $2 billion selling shares at $26 in an initial public offering last week.
