Shopify softened a little over the holidays but had a strong bullish punch on Jan2. Earnings coming up at the end of January, so I expect a retest of the 50-day SMA and continuation higher. We have `JAN 18 2019 SHOP $90` naked puts sold for `$15.00` two weeks ago and `APR 20 2018 SHOP $90` naked put sold for `$3.80` one week ago looks good too.
