Running the example code shown gives the following error:

stock = qs.utils.download_returns('FB')
qs.reports.html(stock, "SPY", output="report.html")

same erroe = IndexError: index 0 is out of bounds for axis 0 with size 0

You need to run downgrade to 0.0.25 They borked the last release pip install quantstats==0.0.25

Have the same error as @AnasEssahal when using qs.reports.full with both returns and a benchmark. Downgrading to 0.0.25 did not fix this error (although downgrading did allow me to run the qs.reports.html with both returns and benchmark without error)

@AnasEssahal Thought might be useful. For my error was "IndexError: index -1 is out of bounds for axis 0 with size 0",

What I did was:

1. Check that ticker name does exist (and correct name) in yahoo finance, since Quantstats retrieve their data from yahoo finance
2. Set 1 yr period or lesser. example qs.utils.download_returns('DOT1-USD', period="1y) as some assets out there are new. this error arises especially if you deal with portfolio. qs.utils.make_index() as some assets are newer than others, hence the data index will not match
