The stock has formed 'spinning top' pattern (just google it for details). It's important that the current 'doji' was formed at the same level as the 'hanging man' pattern from Feb 7.
The r-zone is around ~155 (former s-zone - read old posts for details).
For those really interested in underlying processes, just take a look at the Q4-2017 report where the company, on the one hand, has informed investors they could expect the 'net sales' in Q1-2018 just around ~2.2 bln. However, on the other hand, in the same report Q4-2017 the company has reported the 'net booking' of 2.935 bln . That is the 'net sales' in Q1-2018 must actually be well above 3.1 bln.
Indeed, taking into account the exact definition for the 'net booking' (take a look at the company website), one can see that the 'net booking' reported in the current quarter is just a 'lower limit' for the next quart 'net sales' (this is actually caused by & related to the company 'business-production-sell cycles' - it's actually confirmed by the company reports for the last several years - just take a look).
Thus, an ordinary investor (just may be a bit more advanced) would ask --> why the company forecasts much lower 'net sales' (in the next quarter) than the actual 'net booking' the company actually has. For those are not familiar with the issue --> the 'net booking' in the current quarter is just a 'lower limit' for the 'net sales' in the next quarter (in 99% cases).
This is just an example of the company 'reporting' (upwards price manipulation). We'll provide a systematic analysis for the issue soon. Though, all profs knows all these stuff very well.
Nice weekend everybody.
