I was able to buy $CBIO  Entry 9.50 , Exit 17.38 for $15k+ profit using my  charles schwab account and TDameritrade scanner using Arick Russel pre-market scanner settings.  The catalyst was IND new drug approval from Korean Ministry of Food and Drug safety.  I also read the SEC exchange filings from SEC.GOV and entering the ticker symbol "CBIO" under search box "Edgar Filings" by scrolling mid way down the web page. I use the Toni Turner "beginners guide to day trading" a 17 year old book I got from the $1 store.  I'm only on chapter 5 because I have ADHD and I find it very difficult to concentrate. That you Mr. Turner. 

 

 

This may warrant additional research from who ever reads this. I've also noticed these stocks have dropped significantly In pre-market. (reason in SEC filing at SEC.GOV)  In the Search Edgar Filings, enter the stock ticker.  

$PULM March 17, 2017 after hours, plummet down to $2.34 from $3.10   (after market) 

$HTGM  March 28,2017   $12.00 down to $7.22 

$CERU  March 20, 2017  Down to $1.00 from $3.58

 

Please check your Securities and exchange filings prior to engaging in a trade.  The answers to the drop in stock price maybe inside the SEC.GOV filings. 

 

Please be careful of other chat rooms, they are seriously full of pump and dumps ready to take your hard and cash.  They may look very interesting and "witty" but buyer beware. 

 

My suggestion, stay away.
