I did buy some last year too. In August. Though most of my gains have come from my initial purchase in 2014.
At opportune times, I add more. Valuations for Symphony have been sky high since 2015…though by its lofty valuation standards it does fall and it does give some entry points (even those entry points are always at high valuations )
The promise of growth for years to come - both local and global is the reason I continue to hold the stock and add on declines. Also, the other thing I have noticed is the earnings here don’t grow in a linear fashion. You’ll have a one or two bumper years followed by one or two years of low growth. Overall though it is expected to continue to grow well.
Plus the management is really good too. Very shareholder friendly and transparent. They are also very focused on innovation - they keep coming up with new products within air coolers (Damn Cool ). Though I hate their Annual Reports, I think they try too hard with it.
All in all a brilliant company to hold and be invested in (at least IMHO).
