Today’s tickers: LULU, ELN & POT LULU  - Lululemon Athletica, Inc. –  Shares in the maker of high-end athletic apparel are taking a breather today, trading down 1.95% at $72.79 as of 12:30 p.m. in New York after closing at a record-high of $74.25 on Thursday. A large block of LULU call options purchased in the first 30 minutes of the session suggests at least one strategist may be positioning for the price of the underlying to stretch to new heights in the near term. The Company is scheduled to report fourth-quarter earnings ahead of the opening bell next Thursday. Options volume on Lululemon is heaviest at the April $80 strike, where more than 13,700 contracts changed hands against open interest of 1,291 positions. The single largest print, a block of 12,551 calls, appears to have been purchased for a premium of $1.60 per contract. The trader responsible for the transaction may be taking an outright bullish position on the high-flying apparel retailer, although, it’s possible the strategist is short the stock and buying the calls as a hedge. If the trader is making a purely bullish bet on LULU ahead of earnings, profits are available on the long calls in the event that the price of the underlying jumps 12.1% to top the effective breakeven price of $81.60 by expiration next month. Meanwhile, a put spread initiated in the weekly options indicates another trader is prepared for the shares to decline post earnings. It looks like a roughly 1,150-lot Mar. ’23 $65/$70 put spread was purchased at a net premium of $1.15 per contract, thus yielding profits or downside protection should shares dip down to the $70.00-level during the next five trading sessions.
