As far as an investment goes, Sony is a mess and has been a mess for quite some time ...
This isn't a comment on the quality of their products, but is more an observation that in almost all of their markets they're spending more money chasing after fewer sales because they're facing stronger competition from more innovative and/or inexpensive products; or the market has fundamentally changed and Sony has yet to adapt.
Since they're so diversified your money is likely safe, but you will probably see a much better return by investing in an index fund.
