Yes...but all fund companies have an expertise in a specific area, regardless of how they market themselves. In general if you're looking for equity funds, you're better off steering clear of all fund companies and focus on the ETF market. It is far more cost effective, and the track record of fund managers measured against the broad market is consistently embarrassing to the mutual fund industry.
In the fixed income markets, I believe there is a benefit to active management, as the bond market, unlike the stock market is extremely inefficient in terms of pricing. Franklin has a number of Municipal Bond funds that are among leaders in the field. Muni's in particular are a very challenging field to manage, and will probably remain so for the next few years. This is where I would suggest their expertise is. Be advised that many of their funds have sales charges. As an investment advisor, they are waived for me and my clients. But you as the retail investor will not get the NAV as a price. So if you're buying them on your own, you may want to be conscious of the sales charges and possibly look for a comparable competitor product.
