BEARS ARE IN , Tata communication

I just want to share interesting price history of tata communication, It has rewarded the investors with full hand.On November 1 2000 stock got split from 3;1, at the price of 348 . may be stock price was 116 and made a low 71. it took 3 years to get this low.And within span of 4 years, I mean to sayin 2007 it made an high of 750.Is it AMAZING? Then what Happenned? From 2007 it started falling to the level of 118. From 2013 to 2017 4 years of time made another high of 767. It has made double top .Is the history repeat? Is it time for long time investors to book profits and stay away? or will it move towards the next ltrajectory. Anyone very good at fundamental analysis guide. weekly chart showing tiredness, Engulfing candle has eaten away the two months price action. Possibility of 585 in two months time frame?
