Is HXG a "hyper-growth stock" too

I see that Port Phillip Publishing, via the Resource Speculator newsletter, have just recommended 3 "hyper growth stocks" today in a new report. These 3 stocks, they say, have the potential to make investors millionaires by Christmas!!.. Two of the stocks are lithium plays and the third is a cobalt stock. Reading the report made me think, surely if those 3 stocks can return exponential gains, why couldn't Hexagon do the same this year as high quality graphite is also an important component in the lithium ion battery? Have the punters forgotten how important and valuable graphite is in the process because it's price is not traded like the other materials?
I bought more HXG today as I think it is flying under the radar myself. There is lots of news to be released over the next few weeks so I hope to see a strong rerating
