Frequently asked
Common questions.
Are CLS historical prices split-adjusted on TECHi?
Yes — TECHi applies universal split adjustment across the entire history (including the IPO close and all-time high/low calculations). This is why long-term CAGR and performance numbers stay accurate instead of showing the bogus pre-split prices you sometimes see elsewhere.
How does TECHi calculate total return and realized volatility for CLS?
Total return columns back out actual dividend reinvestment. Realized vol is annualised 30-day rolling log-return stdev × √252. These documented series power Forward model inputs and historical validation checks.
Why does CLS historical data on TECHi look different from other sites around splits or dividends?
Many platforms serve unadjusted or partially adjusted series that break long-term charts and CAGR. TECHi normalises the full history once using the verified split list, then derives every derived metric (CAGR, all-time high/low, progress windows) from that single source of truth.
Can I export CLS historical data for backtesting?
The page renders the full OHLCV table with return and total-return columns. Export buttons (CSV) are available on the companion financial statements pages; the same disciplined data layer underlies everything.
How far back does the CLS history go?
TECHi defaults to one year of daily bars for speed. The underlying feed reaches to Celestica Inc.’s IPO. MAX on the Chart page loads the complete adjusted series for long-horizon analysis.
