That's fundamental analysis, not technical analysis.
I agree, if you devote a large amount of time to it and you're very good and just a little lucky, double-digit returns aren't at all out of reach, even in bad markets, but you generally have to accept volatility as your returns increase. Strictly speaking, any returns over the RFIR is going to force you to accept volatility. For non-pros, 8-9% will generally give growth that'll stay ahead of MMA+inflation with low enough volatility that they don't flip their shit in a market downturn.
Government bonds in general are good IF your income is high enough that you need the tax savings. You'd have to have a really high income base and a whole load of extra income dedicated to investments in tax-free bonds to get you even with an 8-9% return though. Plus, with the state ones, you need to worry about how mobile you are (hope your job doesn't move you out-of-state) if you want to realize the tax advantage completely.
Regardless, as to the OP's question, TA is bullshit and no reputable financial mathematics course will teach a single fucking thing about it other than that fact. Most financial mathematics these days are focused on risk control rather beating the market.
