Party City Holdco Inc PRTY announced Monday it will open about 50 pop-up toy stores for the holidays to seize the market Toys 'R' Us abandoned. The Street responded to late reports with a 2-percent stock pop, but one analyst said Party City’s foray into toys wasn’t unexpected. “I think it’s been well-understood by investors that other retailers would step up to the plate to take the opportunity to gain some of TRU’s 15 percent share of the toy retail market in the U.S., so the news about Party City’s action does not come as a big surprise,” D.A. Davidson analyst Linda Bolton Weiser told Benzinga in an email. SourceStochastics are heading down from the overbought territory, so the downside takes place.
