When an IPO forms a green line top (does not go through it for a minimum of 3 months) and subsequently breaks through the green line to an all-time high (GLB), it can be the start of a major up-trend. It took a lot of buying interest for SHAK to come back after it fell from 96.75 in 2015 to a low of $30 in 2016. Now it has broken out and merits attention. See this monthly chart. I tweeted this GLB Wednesday intraday (follow me @wishingwealth to get my tweets). A close back below the green line would negate the GLB.
What about GLBs, for 52 week highs? Earlier entry in SHAK
