Strategy in a nutshell

The investment universe consists of all cryptocurrencies with daily price, volume, and capitalization data available on https://coinmarketcap.com/. Assets with a market cap of less than 1 million dollars and those with a trading history shorter than 60 days are excluded.

To proxy for geopolitical risk, the GPR index is constructed following Caldara and Iacoviello (2022). It is based on calculating the frequency of geopolitical event-related articles in major newspapers.

Now geopolitical beta is calculated using a rolling time-series regression of excess daily returns on a daily change in GPR and the following control variables: excess returns on the market, size, and momentum factors. The equation can be found on page 4 of the paper. The estimation period is 21 days, but it is robust to adjustments.

Sort the cryptocurrencies into value-weighted quintiles according to their geopolitical beta. Long the lowest geopolitical beta quintile, short the highest. Rebalance weekly.

Economic rationale

The GPR index, formerly constructed by Caldara & Iacoviello, is a measure of the geopolitical risk in the world. By approximating the geopolitical beta based on this index for a given cryptocurrency, its sensitivity to geopolitical events is measured. The results support a hypothesis that investors are likely to be willing to pay a premium for assets with low geopolitical beta. Therefore, price and geopolitical beta are negatively correlated, which is the base idea of this strategy.

Entry & exit

Entry

On each month, compute 252-day total return on BTC-USD, ETH-USD. Hold only names with positive absolute momentum, equal-weight.

Exit

Sell a name when its trailing 252-day return turns non-positive. If none remain positive, sit in cash.

Market data required

Needs at least 252 adjusted daily closes on BTC-USD, ETH-USD before the first signal is ready. Crypto columns include weekend rows. The lab loads Yahoo Finance via backtest.data.load_daily_prices.

Symbols

BTC-USD, ETH-USD

Frequency

Weekly · Daily adjusted close; signals rebalance on the month change (last available session)

History needed

≥ 252 trading days per symbol (about 12 months), plus a few extra bars so the first signal can fire.

Fields

Adjusted close (Yahoo auto_adjust)
Session date index

Credentials

None for paper and the onsite lab
Broker or exchange API keys only for live orders

APIs & providers

Quant Buffet Data API

The lab calls load_daily_prices for the ASSETS panel of adjusted closes, then caches CSV so backtests replay the same series.

Provider: backtest.data.load_daily_prices
Auth: None for paper / sandbox backtests
Endpoints: load_daily_prices(ASSETS, start="2000-01-01")

API / docs → /en/docs/data-api

Yahoo Finance via yfinance

ETFs and crypto proxies such as BTC-USD / ETH-USD share Yahoo daily bars (auto_adjust=True).

Provider: yfinance → Yahoo Finance
Auth: None for public history
Endpoints: Ticker.history / yf.download(auto_adjust=True)

Quant Buffet syntax cheat sheet (copy / insert)

Paste these fragments into the editor. The sandbox rejects QuantConnect, os, and network libraries.

Required imports

Only these libraries are allowed in the sandbox.

ASSETS list (whitelisted ETFs)

Module-level list. Tickers must be in the Quant Buffet whitelist.

ASSETS = ["SPY", "QQQ", "TLT", "GLD", "BIL"]

make_on_day contract

Must return (on_day, ready). on_day calls engine.set_target_weights.

def make_on_day(prices: pd.DataFrame):
    cols = [c for c in ASSETS if c in prices.columns]
    sma = prices[cols].rolling(200, min_periods=200).mean()
    state = {"last": None}

    ready = sma.dropna(how="all").index.min() if sma.notna().any().any() else None
    return on_day, ready

Set target weights

Weights should sum to about 1.0. Empty dict = 100% cash.

engine.set_target_weights(dt, {"SPY": 0.60, "BIL": 0.40})
