Vitali Giggy
Data science student in Madrid. I build models, test them against honest baselines, and publish the answer — even when it's no.
- Second year, Data and Business Analytics, IE University
- Co-founder, IE International Student Community
Selected work
Each project asks a question, sets the pass/fail bar before testing, tests against baselines, nulls and placebos, and publishes the verdict — even when it is “no edge”.

Music Equities
Can public attention data forecast a music company's quarterly revenue before it is reported, and if so, had the market already priced it in?
VerdictNo edge

ERCOT DART spreads
Can the day-ahead vs real-time power price spread at ERCOT be predicted from publicly observable forecast errors?
VerdictStrong link, no predictive edge

market-sim
Are chart patterns real? Build a market where every trader is a coin-flipper, and see whether support, resistance and channels still show up.
VerdictPatterns appear from pure noise

Sector timing
Trend rules seemed to time energy and construction stocks well. Is that timing edge real, or an artefact?
VerdictRejected: market exposure, not timing skill
How I work
Ask a question
Each project starts from one plain question that a test can answer.
Example: Sector timing
Set the bar first
The pass/fail criteria are written down before any test is run, so the result cannot move them.
Example: Music Equities
Test against nulls
A result only counts if it beats honest baselines, nulls and placebos.
Example: market-sim
Report the verdict
The answer gets published as it came out, even when it is “no edge”.
Example: ERCOT DART spreads
